Support Codex's Collaboration Mode

[travisjeffery]

Re: #263 (comment)

Codex has a Collaboration mode that's very similar to Claude's Plan mode. It seems like codex-acp has at least some support for it: https://github.com/search?q=repo%3Azed-industries%2Fcodex-acp+collab&type=code. Essentially if same support/flow for Claude's plan mode by using agent-shell-set-session-mode to collab when using Codex it'd be awesome.

Checklist

• I've read the README's Issues section.
• I'm running the latest agent-shell version.
• I'm running the latest agent version (ie. Claude Code, Geminig CLI).
• I'm running the latest agent ACP package (ie. claude-code-acp).
• For requesting new agent support, I'm including a link to the ACP-capable agent or related ACP package.
• For issues, I'm including ACP traffic (as per README).

Thanks for filing. Doesn't look like this feature is exposed by Codex to ACP yet? I don't see it listed in the available modes (which is what Claude uses).

▼ Available modes

Read Only (read-only)      Codex can read files in the current workspace. Approval is required to edit files or access the internet.
Default (auto)             Codex can read and edit files in the current workspace, and run commands. Approval is required to access the internet or edit other files. (Identical to Agent mode)
Full Access (full-access)  Codex can edit files outside this workspace and access the internet without asking for approval. Exercise caution when using.

I had a quick search through all the Codex traffic for "collab" and didn't find anything. Do you have more details?

[travisjeffery]

Yeah I wasn't quite sure looking at the ACP if what was there was sufficient or not. I don't have more details. Seems it's not possible now. Shall I close and re-open later if they add it or keep it open for others to see?

Maybe file a feature request with codex-acp project and we link them up?
